ESD level of the module: Human body model (HBM) is 2000V, charged device model (CDM) is 500V.
Position of ESD protected components should be reserved if the products require higher ESD requirement such as
pins connect to USB and SD-card.
EMI should be aware when the module operated by connecting external wire. Using shielding wire or
reserving common mode choke could avoid EMI.
